About 0NQL4ZZ

0NQL4ZZ is the ICD-10-PCS code for a repair procedure on the left palatine bone using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other facial bone repair, the ICD-9-CM procedure title it maps to (76.69).

For a different body part, codes include 0NQ04ZZ (skull), 0NQ14ZZ (frontal bone), 0NQ34ZZ (right parietal bone), 0NQ44ZZ (left parietal bone), 0NQ54ZZ (right temporal bone), 0NQ64ZZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NQL0ZZ (open), 0NQL3ZZ (percutaneous) and 0NQLXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
